Abstract: Immunogenic compositions for administration to adults particularly to the elderly, to protect them against disease caused by infection by respiratory syncytial virus and influenza virus comprise an immunoeffective amount of a mixture of purified fusion (F) protein, attachment (G) protein and matrix (M) protein of RSV and an immunoeffective amount of a non-virulent influenza virus preparation. The components of the composition when formulated as a vaccine for in vivo administration do not impair the immunogenicity of each other. The immunogenic composition may also contain an adjuvant.

Abstract: The fusion (F) protein, attachment (G) protein and matrix (M) protein of respiratory syncytial virus (RSV) are isolated and purified from respiratory syncytial virus by mild detergent extraction of the proteins from concentrated virus, loading the protein onto a hydroxyapatite or other ion-exchange matrix column and eluting the protein using mild salt treatment. The F, G and M proteins, formulated as immunogenic compositions, are safe and highly immunogenic and protect relevant animal models against decreased caused by respiratory syncytial virus infection.

Abstract: Methods and compositions for enhancing an immune response to an antigen in a host are provided. Immunogenic composition comprising an antigen and an amount of purified M protein from respiratory syncytial virus are provided in a pre-selected amount to provide an enhanced immune response to said antigen in a host having a pre-existing respiratory syncytial virus M-specific immune response. The antigen can be an antigen from Respiratory syncytial virus.

Abstract: Antibody molecules specific for surface structures of antigen presenting cells that have been modified to include an antigen moiety at a specific site therein to produce novel conjugate antibody molecules are disclosed. These conjugate molecules are produced by genetic modification of genes encoding light and heavy chains of the surface structure specific antibody, and expression in mammalian cells to produce the conjugate antibody. The conjugate antibody retained specificity for antigen presenting cells and contained the antigen moiety. The conjugate antibody molecules deliver the antigen to antigen presenting cells to produce an enhanced immune response to a host immunized therewith. The conjugate antibody molecules and nucleic acid molecules encoding them are useful as antigens and as immunogene in diagnostic and prophylactic applications.

Abstract: An immunization strategy to provide protection against disease caused by infection with paramyxoviridae viruses, specifically respiratory syncytial virus (RSV) and parainfluenza virus (PIV), is described. A primary administration of a live attenuated strain of RSV or PIV first is made to the host followed by a booster administration of at least one purified RSV or PIV protein or immunogenic fragment thereof, which may be adjuvanted with alum. This immunization strategy provides a safe and effective means of controlling disease caused by RSV and PIV infections. The strategy leads to a stronger protective immune response than other strategies and to the induction of a more balanced Th-1/Th-2 type response than previously attained.

Abstract: An immunization strategy to provide protection against disease caused by infection with a paramyxoviridae virus, specifically respiratory syncytial virus (RSV) and parainfluenza virus, is described. A priming intranasal administration of a recombinant virus expressing at least one RSV or PIV protein or immunogenic sequence there first is made to the host followed by a booster administration of at least one purified RSV or PIV protein or immunogenic fragment thereof, which may be adjuvanted with alum. This immunization strategy provides a safe and effective means of controlling RSV and PIV infections. The strategy leads to a stronger protective immune response than other strategies and to the induction of a more balanced Th-1/Th-2 type response than previously attained.

Abstract: In summary of this disclosure, the present invention provides hemagglutinin-neuraminidase (HN) and Fusion (F) glycoproteins isolated and purified from parainfluenza viruses types 1, 2 and 3, methods of producing the same, and uses thereof in immunogenic compositions and diagnostic embodiments. In particular, a trivalent vaccine containing HN and F glycoproteins from PIV-1, PIV-2 and PIV-3 generated an immune response capable of neutralizing each of the virus types. Modifications are possible within the scope of the invention.
